50a6df89b8 Fix Lua type of zero
This change fixes a regression from 281a0f27 which resulted in the
integer literal `0` being interpreted as a floating point number. This
should also fix a reported issue with Fennel integration.

fe5c475f83 Add Deflate() / Inflate() to redbean and fix bugs
The Compress() and Uncompress() APIs were a mistake. The functions
themselves work fine, but it's a design blemish and does superfluous
work. Since they were only introduced in the last few weeks, they're now
deprecated and references to them have been scrubbed from the website
and other documentation. Please use the new APIs since the old APIs will
be removed at some point in the future.

This change introduces automated Lua unit tests for the Redbean APIs.
There's a few functions that were broken which have now been fixed, e.g.
Underlong() and Decimate().

Scan fixed-width integers in vcscanf (#424)
When a format string like %2x is provided, the width parameter was read
correctly as 2, but it was not used when decoding the number from the
input string (ie instead of reading 2 characters from the input string,
vcscanf read all the characters).

This change uses the value of width within the number decoding loop to
read fixed number of digits correctly. if width is zero (not provided),
the default of width is set as bits.

f79b2fe23a Change assumptions about PROT_EXEC implying PROT_READ
On all operating systems tested so far, PROT_EXEC without PROT_READ
always makes memory readable. This turned out to not be the case on
Chromebooks, which likely means they have the capability of running
programs which aren't able to read their own code.

d5312b60f7 Make improvements to locking
This change makes pthread_mutex_lock() as fast as _spinlock() by
default. Thread instability issues on NetBSD have been resolved.
Improvements made to gdtoa thread code. Crash reporting will now
synchronize between threads in a slightly better way.

This change hardens the code for opening /zip/ files using the system

needed for low level allocations.

8b72490431 Make mutex calling code 10x tinier
Calls to lock/unlock functions are now NOPs by default. The first time
clone() is called, they get turned into CALL instructions. Doing this
caused funcctions like fputc() to shrink from 85 bytes to 45+4 bytes.
Since the ANSI solution of `(__threaded && lock())` inlines os much
superfluous binary content into functions all over the place.

c260345e06 Make locks more reliable
This change switches most of the core locks to be re-entrant, in order
to reduce the chance of deadlocking code that does, clever things with
asynchronous signal handlers. This change implements it it in pthreads
so we're one step closer to having a standardized threading primitives

701564de19 Perform better fixups of NT paths in execve()

c:/foo.bar paths on Windows when generating the CreateProcess() cmd line
thus fixing a regression that happened in the last two months when using
the help() feature of Actually Portable Python in the CMD.EXE shell.

13ee75150c Improve redbean plus code size optimizations
This change turns symbol table compression back on using Puff, which
noticeably reduces the size of programs like redbean and Python. The
redbean web server receives some minor API additions for controlling
things like SSL in addition to filling gaps in the documentation.

de5de19004 Make improvements
- Document redbean's argon2 module
- Fix regressions in cthreads library
- Make testlib work better with threads
- Give the cthreads library lots of love
- Remove some of the stdio assembly code
- Implement getloadavg() across platforms
- Code size optimizations for errnos, etc.
- Only check for signals in main thread on Windows
- Make errnos for dup2 / dup3 consistent with posix

This change also fixes a bug in the argon2 module, where the NUL
terminator was being included in the hash encoded ascii string. This
shouldn't require any database migrations to folks who found this module
and productionized it, since the argon2 library treats it as a c string.

8f12cd980d Fix execution bug w/o binfmt_misc
The longjmp relocation in the master boot record coincidentally had a
quote character in it, which caused the master boot record to be used
when interpreter by the shell. The solution, is to move the grub stub
below the long mode loader so the real mode loader relocation is near
the master boot record. This change includes a regression test.
